Fluorocarbon

I've been playing on ebay all day and ran across Frenzy's fluorocarbon. They say it is a smaller diameter than other fluoro's. Has anyone put this to the test? I would imagine that is made by a major fluorocarbon manufacturer. I've been using Seaguar and Momoi without any problems. The frenzy is very well priced.
